Hold-in coil open circuit test
WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.
Check for continuity between magnetic switch "S" terminal (1) and coil case. If there is no continuity, coil is open and magnetic switch should be replaced.
